Letters Paten-t No. 103,7 62, dated May 3]., 1870.

IMPROVEMENT IN MACHINERY FOR MAKING- BARREL-HEADS.

The Schedule referred to in these Letters Patent and making part of the same To all whom. it may concern:

Be it known that I, WVILLIAM MICKEL, of Oneonta, in the county of Otsego and State of New York, have invented a new and useful Improvement in Machines for MakingBarrel-Heads, of which the following is a full, clear, and exact description, reference being had to the accompanying drawing forming part of lthis specication,iand in which- Figure 1- represents a plan, and

Figure 2, a vertical section, taken as indicated by the line a: :t in fig. 1, of a machine for making barrelheads, constructed according to my improvement.

Similar letters of reference indicate corresponding parts.

.My invent-ion consists in a certain arrangement of various vslides carrying suitably-constructed cutters,v

together with-a revolving face-plate and clamp, be-

tween whichthe stu' is held, for cutting barrel-heads of di'erent sizes, by rst rounding them and afterward forming the opposite bevels on their edges, snb- In the accompanying drawing A represents the frame of the machine, and

B, its operating-shaft, speeded up by gearing', a b, that may be set in motion by any suitable power.

On this shaft B, which lies horizontal and in transverse relation with the frame, is a iTy-wheel, D, to

y'give steadiness to and .ease the working of the machine.

Said shaft, on its front end, carries a face-plate, E, of lesser diameter than the smallest barrel-head to be made, and provided with a center, c, and pointed projections d, for centering and holding the stuff of which the barrel-head 'is to be formed, and which, having a center marked on it, is pressed up against the face-plate and held securely thereon by a many-- armed clamp, F, provided with a center and operated by a screw from the front of the machine.

To facilitate the centering of the stud' on the faceplate E, when introducing it between the latter and the clamp, said faceplate is provided with a series of holes, e, through it, which apertures give light from the rear down on the center c, to adj ust the stui' to said center, after which the clamp F is tightened up i to fix the wood on the face-plate and secure its rotation with the latter. v

G isa sliding block arranged on one side of the shaft B, and adjustable to or from the latter, and held, when adjusted, .by a se'tuscrew, f.

In this sliding block is a cross-slide, H, operated by' hand through a lever, I, and carrying at its front end determined, according t0 the required size of the barrel-head, by the adjustment of the sliding block, which adjustment is made and fixed before projectingthe cutter y to perform its work.

yThe barrel-head having been thus sized and rounded,

Vthe cutter y is drawn back bythe level' I anda second slide, J, arranged in transverse relation with the slide H, and carrying,reversely-disposed or beveling cutters h h at its forward end, pushed forward to out simultaneously the necessary opposite bevels on the edge of the wooden disk or barrel-head to adapt it to the groove inthe barrel, said cutters h h being made ad.- justable to suit different thicknesses of stni` orsi'zes of barrel-heads.

The slide J is then run back, the clamp F slackened, and the iiuished' barrel-head removed.

The sliding block Gis not disturbed from its adjustment when itis required to make a series of barrel-heads of the same size.

By this machine, barrel-heads of various sizes may be made with accuracy and dispatch.

that is here claimed, -and desired to be secured by Letters Patent, is

The arrangement of the Vs lide J provided with reverse beveling cutters' h h-,thesliding block G, and transverse slide'H, with its4 cutter g, the lever 1,*the face-plate E,-and clamp F,'the whole being constructed and operating essentially as specified.
